Thanks for telling us about this... Nothing inovative, but nice to = know. However, I'm not so sure I'd want to run it on a flash memory device! Any virtual disk is going to do quite a few writes, and flash memory can = only do so many before it starts to fail. It's worse with an OS that does a swap file (such as BartPE (WinXP) or = Win9x on a flash device), but even for a non booting drive, the = directory structure could still go through a lot of writes. (Especially = if the OS modifies the 'file accessed' time for a file that gets = accessed often.) Sure, flash memory can do many writes, but it only takes a single bit to = fail to cause problems and possibly make it impossible to get important = stuff off that virtual disk. And directory structures are prime = candidates for failing first. It would have been better if they had done something to set up a small = ram disk to hold things, and then copy it back to the device when you = get done.
